your canal is not realistic (speaking as someone that has a narrow boat on a canal)
1. you need a ton of weeds at both sides to make it hard work for boats
2. you need angry fishermen that dont realise that canals were built for boats not fishing
3. where are the car and lorry tyres?
4. lack of used mattresses' floating along
5. at least 1 shopping trolly at a lock
6. the locks all leak so loads of water should be gushing from the closed lock gates
7. the lock paddle winding should have out of order signs on 1/3 of them
8. usual these days to have a body floating along, or at least a car part submerged
other things for good measure (as found rapped round my prop this year)
boxer shorts, string, rope, bin liners, plastic, barbed wire
Other than that looking good, bet it stinks of saddleworth moor fire today though! we can smell it over here in westhoughton.
